I don't know you reloading proficiency, therefore forgive me if I could appear somehow picky, but is my opinion that, whatever your reloading task, your press, your rifles, a cheap Lee Universal Decapping Die could be really a smart buy_ I've the sensation that, working on an auto platform, could be quite normal decapping and priming without cleaning the p.pocket in between : that, if heavy debatable on bolt actions, could give even worst problems on semiautos: the un-removed crud could cause the seating of the next cap not deep at safe enough level, with unforeseen consequences_
Some people would think differently, but I really advise you to stay on the safe side, decapping separately your brass and cleaning the pockets, maybe losing more time, but giving to your rifles and to yourself an happier and longer life_
I'm not-so-wise, but that's my sincerest word to the wise...etc.._
